Can we have a curated TOC / searchable databse?
Yes. This can be built in R using the ghql package to access the GitHub API (v. 4). We can create a dataframe of repos and their metadata and use that to build whatever we want. This can also be used to track things in a simple way. A curated list would require pulling in the repo "Topics" as well.
Eric has R code to scrape Drakelab orgs and pull project names and metadata into a dataframe. From there it can be dumped into HTML code if desired.
